1、 Sowing and propagation

1. Soaking seeds and accelerating germination: treat the seeds before sowing, soak them in clean water for 2 hours, remove them and then put them into 55 ℃ hot water for another 4 hours. During this period, stir frequently to avoid scalding. Soak in clean water and soak in trisodium phosphate solution for 20 minutes, which can avoid some diseases

2. Soil preparation: the soil should be loose, water, fertilizer and breathable. After preparation, it can be laid on the sowing bed or put into the seedling tray

3. Sowing: after the seeds are treated and the soil is ready, sowing can be carried out. There are three common methods: drill, broadcast and on-demand. Either way, cover the soil immediately after planting. Its planting has no requirements for time, but if it is selected in winter and spring, it should be covered with plastic film, and if it is covered with shading net in summer and autumn, it will soon grow seedlings

2、 Cutting propagation

Cutting method is also very common. To choose strong branches, remove the leaves below and leave three or four above. After treatment, soak it in clean water, and white roots can grow in three or four days. Pay attention to changing the water every day during this period to ensure that the water quality is clean. After growing roots, plant them directly into the flower pot. Pay attention to the invisible light in the initial stage, and then slowly bask in the sun three days later to avoid sunburn
